Abstract
The utility model discloses a sealing device of a wind driven generator gear case output end, which relates to the technical field of the sealing device of the wind driven generator gear case output end used for a pitch control gear case. The sealing device of the wind driven generator gear case output end comprises a case body, a tapered roller bearing, an oil seal and an output shaft, wherein the inner wall of the end of the case body is provided with the tapered roller bearing; the case body is connected with the output shaft through the tapered roller bearing; the oil seal is arranged between the case body and the output shaft; a shaft sleeve is arranged between the oil seal and the output shaft; the oil seal is a framework-type double-lip structure; and the lip mouth of the framework-type double-lip structure is in direct contact with the outer wall of the shaft sleeve. The utility model achieves the goals of few packaging parts, simple machining process and convenient assembly process.
Description
Technical field
The utility model relates to a kind of seal arrangement of gear-box output terminal, especially a kind of seal arrangement that is used for the wind-driven generator wheel-box output terminal of variable propeller gearbox.
Background technique
Along with developing rapidly of global renewable energy sources market, wind-power electricity generation becomes the energy industry new growth point gradually, has possessed the ability of competing mutually with other generating means, worldwide presents the gesture of rapid growth.
Driftage is one of vitals of wind-driven generator with variable propeller gearbox, and its effect is the angle that is used for regulating engine rooms of wind power generators and blade, makes its variation that adapts to wind direction or wind-force, thereby more effectively utilizes wind energy.Because operating mode is more abominable, inconvenient maintenance adds that installing space is narrow and small, and variable propeller gearbox is to reliability, weight, boundary dimension and the requirement that strictness is all arranged is installed.At present, the output terminal of variable propeller gearbox seals with saturating lid, oil sealing is contained in cover, and oil seal lip contacts with output shaft.This seal arrangement need be processed lid, thread mill drilling on casing, and the quantity of part can increase, and assembling is complicated.
Summary of the invention
The utility model provides a kind of encapsulating parts few, and manufacturing procedure is simple, and assembly process is the seal arrangement of wind-driven generator wheel-box output terminal easily.
The purpose of this utility model is achieved in that a kind of seal arrangement of wind-driven generator wheel-box output terminal, comprise casing, tapered roller bearing, oil sealing, output shaft, the inwall of casing end is provided with tapered roller bearing, casing is connected with output shaft by tapered roller bearing, between casing and the output shaft oil sealing is set; Between oil sealing and the output shaft axle sleeve is set, oil sealing is skeleton lips structure, and its lip directly contacts with the axle sleeve outer wall.
Casing of the present utility model is driftage or variable propeller gearbox.
Interference fit between axle sleeve of the present utility model and the output shaft
Advantage of the present utility model is: because oil sealing is installed in the casing, its lip directly contacts with the axle sleeve outer wall, has reduced manufacturing procedure and number of spare parts, provides cost savings, and is convenient to assembling; Lips structure oil sealing can play leakproof dust-tight double action simultaneously; Simple in structure, can be used for various different boundary dimension under requiring driftage or the output terminal of variable propeller gearbox.
